Given the functions f(n) = 500 and g(n) = (nine tenths)n − 1, combine them to create a geometric sequence, an, and solve for the

masya89 [10]

Answer:

$A(n) = 500 * (\frac{9}{10})^{n-1$

$A(11) = 174.34$

Step-by-step explanation:

Given

$f(n) = 500$

$g(n) = (\frac{9}{10})^{n-1$

Represent the combination of f(n) and g(n) with A(n)

So, we have:

$A(n) = f(n) * g(n)$

This gives:

$A(n) = 500 * (\frac{9}{10})^{n-1$

To calculate the 11th term, we make use of n = 11

$A(11) = 500 * (\frac{9}{10})^{11-1$

$A(11) = 500 * (\frac{9}{10})^{10$

This gives:

$A(11) = 500 * (0.9)^{10}$

$A(11) = 500 * 0.3486784401$

$A(11) = 174.33922005$

Approximate to 2 dp

$A(11) = 174.34$

Line CD bisects AB at point C. Find AC if AB = 56 feet

RideAnS [48]

Answer:

AC = 28 feet

Step-by-step explanation:

Point C is the midpoint of AB, so AC is half the length of AB:

AB/2 = (56 ft)/2 = 28 ft = AC

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 less than its length. Find the length and the

hram777 [196]

Perimeter = 72m
length = x
width = x - 4

P = 2l + 2w
72 = 2x + 2(x - 4)
72 = 2x + 2x - 8
72 = 4x - 8
72 + 8 = 4x
80 = 4x
80/4 = x
x = 20

Therefore, the length = 20m and width = 16m
